<P>PROBLEM TO BE SOLVED: To provide a lighting system, a slit lamp using the lighting system and a microscope enabling miniaturization and suppression of heat generation and suppressing the uneven brightness. <P>SOLUTION: A light source part 20 is provided with a first light emitting element group 24 comprising a plurality of light emitting elements 21 disposed in parallel to a reference surface, and a second light emitting element group 25 comprising a plurality of light emitting elements 21 disposed in the front/rear along the optical axis of illumination light emitted from the first light emitting element group 24 in a clearance portion non-interfered with the respective light emitting elements 21 of the first light emitting element group 24 viewed from the optical axis direction and forming a three dimensional arrangement. This lighting system is provided with an insertion hole 51 getting narrower from one end side toward the other end side, the light source part 20 disposed in one end side of the insertion hole 51, a reflecting means 52 reflecting the illumination light and provided in the inner wall of the insertion hole 51, and a guide member 50 guiding the advance of the illumination light by the reflection of the illumination light in the reflecting means 52. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
